Given that the Ford F-Series has been the best-selling vehicle in both the United States and Canada for what feels like forever, it’s no surprise that the company’s upcoming 2015 model has caused plenty of concern.

Both the unproven aluminum-intensive construction meant to drastically decrease weight and Ford’s increased reliance on its turbocharged EcoBoost engines have some people worried if the combination will be successful in the long run.

Some important details about two of the new engines have been made public, and are impressive enough on paper.

The 2.7-liter V6 EcoBoost will have 325 horsepower and 375 pounds-feet of torque

Base models will get a 3.5-liter V6 with 283 horsepower and 255 pounds-feet of torque, which means conventional tow ratings of 7,600 pounds, and a max payload of 1,910 pounds. The old 3.7-liter in current trucks produces 302 horsepower and 278 pounds-feet of torque, but potentially 700 more pounds of curb weight has much lower figures for both payload and towing.

The new 2.7-liter EcoBoost V6 will be the second step up the F-Series ladder, with 325 horsepower and 375 pounds-feet of torque; its maximum payload will be 2,250 pounds and tow rating is 8,500 pounds.

Ford announced that it will follow the new Society of Automotive Engineers (SAE) J2807 towing standards, which means the figures released will be directly comparable to its rivals. The company also proved in a video that the new 2.7-liter EcoBoost is capable of matching or beating its rivals with conventional V8 or diesel V6 engines during measured head-to-head testing at the long upgrade road at Davis Dam in Arizona.

Ford has already confirmed that the 3.5-liter EcoBoost V6 and 5.0-liter V8 will carry over between generations, but whether outputs will be tweaked higher to maintain a proper gap with the new 2.7 EcoBoost remains to be seen.
